Trying to write my first unit test based on example in the 15 minute tutorial. Resolved most errors thanks to post 731526(*) however I still get an error in the assertSame() call.

Test case as follows:

package org.domainmodels.Ooa.test

import org.eclipse.xtext.junit4.InjectWith
import org.junit.runner.RunWith
import org.eclipse.xtext.junit4.XtextRunner
import org.domainmodels.OoaInjectorProvider
import org.domainmodels.ooa.DomainModel

import org.eclipse.xtext.xtend2.lib
import com.google.inject.Inject
import org.eclipse.xtext.junit4.util.ParseHelper
import org.junit.Test
import static org.junit.Assert.*


@RunWith(typeof(XtextRunner))

@InjectWith(typeof(OoaInjectorProvider))
@RunWith(typeof(XtextRunner))
class TestOoa {
	@Inject
	ParseHelper<DomainModel> parser

	@Test 
	def void parseDomainmodel() {
	    val model = parser.parse(
	        "Domain \"Banking\" {
	            Datatype Identifier;
	        }")
	    val domain = model.elements.get(0) as DomainModel
	    assertSame(domain, domain.elements.get(0).type)  //** error here, 'type' underlined in IDE
	} 
}

Error is:

Couldn't resolve reference to JvmIdentifiableElement 'type'.

Relevant section of grammar as follows:

grammar org.domainmodels.Ooa with org.eclipse.xtext.common.Terminals

generate ooa "<url removed due to posting limitations>*"

DomainModel:
	'Domain' name=STRING '{'
	(elements+=ModelElement)*
	'}';
	
ModelElement:
	Subsystem | Datatype | Class | Relationship;

Datatype:
	'Datatype' name=ID';';

//...

Thanks for any help.

Hi,

i dont see a "type" in your grammar. what do you actually want to do?

Hi Christian,

I want to check that:
1. the text fragment is parsed successfully according to the grammar, and
2. an instance of 'DomainModel' is created with the name 'Banking'.

[I obviously misunderstood the code. I thought the 'type' was EMF related, i.e. it was performing my check #2 above).

Thanks in advance.

Hi, no the type in the 15mins tutorial is actually the type of a feature so in your case you might just want to do a assertEquals("Banking", domain.name)
